We tested a Rapid Diagnostic Test (RDT) to detect Trypanosoma cruzi infection using a total of 284 human sera, some of them from provedcases ofChagas disease (n = 145) and healthy individuals from non-endemic areas (n = 139). Another group included was non chagasic serum samples of individuals of other parasitic and non parasitic disease (n = 56), all of them with known serological test results. The RDT had a specificity of 99,3% and a sensitivity of 99,3%. The agreement with ELISA and IFAT was 98,2%. According to the results and the feasibility of the RDT should be an ideal tool for screening purposes in disease surveillance and intervention programs ofChagas disease.
